Edison battery uses graphene
Stanford University researchers have added graphene to a rechargeable nickel-iron battery design invented by Thomas Edison over 100 years ago and used to power 19th century electric cars.
The Stanford researchers used graphene as the conductive element growing nanocrystals of iron oxide onto graphene, and nanocrystals of nickel hydroxide onto carbon nanotubes.
The charging rate of the battery went up 1000 times reducing the time it took to recharge it from hours to minutes.
The Stanford team think that their modification to the Edison battery could see it, once again, used in electric cars.
